iv. Status Register: Enter an OCS Register reference (such as %R100) to indicate
which 16-bit OCS register will have the Ethernet Status word written to it. Table 3.1
shows how this register value is formatted and explains the meaning of each bit in
the Status Word.

v. Version Register: Enter an OCS Register reference (such as %R101) to indicate
which 16-bit OCS register will have the Ethernet Firmware Version written to it. The
value stored in the Version Register is: (Ethernet Firmware Version * 100). For
example, for Ethernet Firmware Version 4.30, the Version register will contain 430.
For the Status and Version registers (if configured), the Direction settings are always
Read Only
vi.
Use CAN ID for last Octet: The Use CAN ID for last Octet checkbox does not
affect Net Mask, Gateway, Status or Version configuration. If the checkbox is
checked then it behaves as follows:
A. If the IP Address Direction combo box is Read / Write, the Use CAN ID for last
Octet checkbox will be unchecked and grayed.
B. If the IP Address Direction combo box is empty or Read Only, the Use CAN ID
for last Octet checkbox will be ungrayed, and can then be unchecked or
checked.
C. If the Use CAN ID for last Octet checkbox is checked, the unit’s 8-bit CAN
Network ID replaces the last (rightmost) octet of the Default IP Address, and the
combined result will be the unit’s IP Address. In this case, if the IP Address
Register edit box contains a valid OCS register, the indicated register will be
loaded with the combined IP Address.
vii. Enhanced Configuration
To perform Enhanced Configuration, first check the Enhanced Configuration
checkbox. In this case, IP Address, Net Mask, Gateway, Status and Version can
all be optionally assigned to OCS registers. By default, the register edit boxes are
empty indicating that no registers are assigned.
